摘要

This paper makes a theoretical analysis of the steady-state creep strain rates and creep rupturing times along the two principal directions of elliptical cell honeycombs using a unit cell model and assuming that solid cell walls follow power law creep and the Monkman-Grant relationship. Based on the results, the effects of the ellipticity of cell walls and relative density of elliptical cell honeycombs on their steady-state creep strain rates and creep-rupturing times can be evaluated. It is found that the Monkman-Grant parameters, m1* and m2*, of elliptical and circular cell honeycombs are equal to that of solid cell walls, ms. In addition, the other Monkman-Grant parameters B1* and B2* decrease as the relative density increases, and B2* is always greater than B1*. Moreover, the creep strain rates and creep-rupturing times of elliptical and circular cell honeycombs are compared with those of regular hexagonal honeycombs with the same relative-density to evaluate the efficiency of their microstructures.
